Was this W10 installation an upgrade from W7/W8+?


Can you follow the Re: [Help] Can't boot to windows (8.1) after resizing partition, because your current MBR points to GPT 4 as bootable disk, not GPT 5? This may not work because you may not have a BIOS/MBR installation of W10 to begin with, but this is worth a test. It only modifies your MBR, but does not change any data.

The current MBR that you have will give you a black screen because there is no OS on GPT 4.


Look at the last line of your Fdisk output, and compare the start/size column values to the entry which is GPT 5 in your GPT output? Do they match?


When you rebuilt the MBR, you used '2 3 4' as your partition list to be hybridized, but you need to use '3 4 5' as your hybrid partition list. Windows will not boot unless you correct this.

Good to see it working. The MBR has a limit of four entries. Under normal circumstances, there is a 1-to-1 mapping between GPT and MBR entries, but you have 5 GPT and 4 MBR entries.


This requires one of the GPT entries to be combined with another contiguous one. In your case, the OS X and Recovery HD are combined to make it look like on MBR entry. You will not be able to see OS X as a separate volume anymore. You have only two usable MBR entries after each of your Windows and Capitan 10 entries are put in separate MBR entries.
